In a study on the dissemination of fake news, users of a social network were classified into two groups: ''susceptible'' and 'not susceptible'. Suppose that in the social network considered in the study, the probability of a randomly drawn user being susceptible is 0.5. In this social network, the probability of a user propagating fake news is 0.9, if the user is "susceptible". Otherwise, this probability is 0.15. Based on this data, calculate the probability: Note: All final answers must be rounded to 4 decimal places of approximation, but do not do any rounding in the middle stages of the solution. a) the probability of a randomly drawn social network user propagating fake news. b) the conditional probability that a randomly drawn user is susceptible, given that he propagates fake news. c) the conditional probability that the randomly drawn user is "not susceptible", since he does not propagate fake news.

“SmartB” owns a phone battery assembly line which provide phone battery to a mobile company. It is known that 4% of the batteries produced by “SmartB” are defective. A random sample of 28 phone batteries is selected from the assembly line and will be sent for inspection. (a) What is the probability that there are exactly 2 defective phone batteries in the sample? (b) What is the probability that all phone batteries in the sample are in good condition? (c) “SmartB” needs to pay a large amount of penalty if there are at least 4 defective phone batteries found in the sample. What is the chance that “SmartB” has to pay this penalty? (d) The production cost of a phone battery is $100 and the selling price to the mobile company is $500. When the phone battery is found defective within a year, it could be sent back for repairment, which costs “SmartB” $70. Suppose all defective phone battery would be reported by the customer within a year and would be sent back for repairment.…

A survey conducted about job satisfaction, showed that20% of workers are not happy with their current jobs. Assume that this result is true for the population of all workers. Two workers are selected at random and it is observed whether or not they are happy with their current jobs. () Draw a tree diagram showing all relevant outcomes andprobabilities.
The department of management studies university of Himachal has ordered text books for the new course in Operating Resarch from Tata McGraw Hills. 50% of these books are printed at Delhi plant, two-fifth are printed at Mumbai plant and the remaining are printed at Calcutta plant. The Delhi, Mumbai & Calcutta plants have respective printing error probability of 0.01, 0.03 & 0.07. If the teacher concerned selects a copy from the shipment & finds it has a printing error, which plant is more likely to print the book”
According to IT department of leading financial firm, 50% of emails received by their employees are spam. They are planning to install a software which filters the spam emails. A reputable cybersecurity brand has launched a software which claims to detect 99% of spam emails. However, they have also reported 5% as the chance of detecting a non-spam email as spam. If an email is detected as spam, what is the probability of it in fact being a non-spam email?
One year, demand for sperm whale oil was particularly high and Captain Ahab decided to hunt onlythose whales. The length of a sperm whale in the 1840s was normally distributed with mean 16.1meters and standard deviation 1.5 meters.(a) What is the probability that the first four whales they catch are all longer than 16.4meters?(b) If the selection and capture of the whales is random, what is the probability that themean length of the first 25 whales they capture is at least 16.3 meters.(c) Upon return to Nantucket, Captain Ahab reports how many whales they caught, andthat the mean length of sperm whales they caught was 16.3 meters. His colleague Captain Bildadexclaims, “But there’s less than a 1% chance of getting a mean that high or higher if the truepopulation mean and standard deviation are what we think they are!”Approximately how many whales did Ahab tell Bildad they caught?(d) The next year, they catch 123 whales with a mean length of 16.4 meters, and astandard deviation of 1.4…
An athletic league does drug testing of its athletes, 10 percent of whom use drugs. This test, however, is only 95 percent reliable. That is, a drug user will test positive with probability 0.95 and negative with probability 0.05, and a nonuser will test negative with probability 0.95 and positive with probability 0.05. Develop a probability tree diagram to determine the posterior probability of each of the following outcomes of testing an athlete.\ A. The athlete is a drug user, given that the test is positive. B. The athlete is not a drug user, given that the test is positive. C. The athlete is a drug user, given that the test is negative. D. The athlete is not a drug user, given that the test is negative. . E. Use the Excel template for posterior probabilities to check your answers in the preceding parts.
Suppose you are studying deliveries made by a shipping company. Suppose you find that 86% of this company's deliveries are made on time. Further suppose each delivery is independent. Finally suppose that you are studying a sample of 15 deliveries from this company. (a) What is the chance that exactly 11 of these deliveries are made on time? (b) What is the chance that less than 14 of these deliveries are made on time? For parts (c)/(d) suppose you are now studying a sample of 950 deliveries from this company. (c) Show why it is appropriate to approximate this situation with a normal random variable. (d) Using the normal distribution, what is the chance that more than 800 of these 950 deliveries are made on time?
